I was thinking about the same thing. I have had a Garmin nuvi 750 and TomTom GO 720, and Telenav literally has at least twice the POI, which are updated in real-time. Also, the maps are also updated in real-time, and for a cell phone, the voice prompts are really clear. I would stick with the telenav service and the car cellphone mount.

If anyone is interested on how to add addresses and/or look up businesses on the web and sync them to their navigator's "favorites", here is the [url=http://signin.telenav.com/tnsso/sso/home.do?callback=http%3A%2F%2Fmy.telenav.... http://my.telenav.com
